Bybit announced changes to the maximum order size for multiple USDT perpetual contracts effective June 9, 2026, at 06:00 UTC.
For CryptoSigy, the useful angle is futures execution quality: order size parameter changes affect bot sizing, partial-fill behavior and position entry timing for algorithmic strategies.
What Happened
Bybit is adjusting the maximum order size for a range of USDT perpetual contracts. These parameter changes take effect June 9 at 06:00 UTC. The change affects some of the most actively traded perp pairs, and bot operators or algorithmic traders using fixed-quantity orders may need to adjust their sizing logic before the change.
Maximum order size changes do not close existing positions, but they can change how large orders are routed, split or rejected. A strategy that sends a single large entry order may need to split it into smaller portions after the change.
Why It Matters
Order size caps affect execution quality for larger positions. If a bot sends an order that exceeds the new maximum, it will be rejected. If the bot splits orders without knowing the new limit, it may experience partial fills, wider spreads or entry delay.
For position-sizing discipline, the trader should verify the applicable max order size for each contract in the signal watchlist. A strategy that was clean at 150 contracts may need to break into multiple legs after the change.
What To Watch Next
Watch the Bybit announcement for the specific contract list and the new max order size values. Audit bot configurations for pairs on the list before June 9 06:00 UTC and adjust order-splitting logic accordingly.
Monitor fill quality and rejection rate in the first hour after the change to confirm the bot's split logic works under the new limits.
